TS-1 has a unique structure, and TS-1/H₂O₂ oxidation system for composition shows excellent catalytic performance in the oxidation of a variety of organic matter. The response conditions of the reaction system are mild, and the ultimate oxidation product is water. It is a typical “green catalytic” system and has received widespread attention from researchers. Here, the synthesis progress of TS-1 to improve the accessibility and activity of active sites by doping mesoporous and microporous structures into traditional TS-1 zeolite in recent five years are reviewed, including hydrothermal synthesis, dry gel conversion synthesis, solvent-free synthesis, microwave assisted synthesis, and isomorphous substitution. Meanwhile, the application of TS-1/H₂O₂ system in oxidative desulfurization, ketone ammonia oxidation, olefin epoxidation, and hydroxylation of aromatic hydrocarbons reactions are summarized and discussed. What's more, the reaction mechanism based on TS-1/H₂O₂ system is proposed on regarding the isolated skeleton Ti site in titanium-silicon zeolite as the active central site. Finally, the challenges and future development prospects of TS-1 zeolite in synthesis and catalytic applications are predicted.
